To all whom it may concern:

Be it known that I, Roy L. WOODARD, a

constituting the subject matter of Patent No.

861,928, granted to me on July 30,1907

The object of the invention is to provide a machine of this character which can be readily set up at the point of use and which is durable and compact in construction.

A still further object is to provide such a machine having means whereby long pipes, drills, etc. can be brought into position to be lowered into a well.

With these and other objectsin view the invention consists of certain novel features of construction and combinations ofparts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a side ele vation of a well drilling machine embodying the present improvements. Fig. 2 is a plan View thereof, the derrick being removed adjacent the base thereof. Fig. 3 is an end elevation of the machine the upper portion of the derrick being removed. Fig. 4 is a side elevation showing the positions of certain of the parts during the operation of positioning a tool upon the machine.

Referring to the figures by characters of reference,Ais thebase frame of themachine made up of mud sills 1, 2,3 and 4 on which are arranged longitudinal beams 5, 6 and 7, the sills l, 2 and 3 being disposed below a platform 8. Disposed upon the sills 2, 3 and 4 and close to the beam 6 are parallel beams 9, and 10 upon one end portion of which is mounted a jack post 11 having a cap 12 thereon from which retaining rods 13 extend downward to a holding plate 14 which 1s disposed beneath the sill 4. Another jack post 15 of similar construction is mounted above the sill 4 and the beam 5 and journaled upon the two jack posts and retained thereon by the caps 12 is a shaft 16 carrying a crank 17 at one end of which is located a wrist pin 18.

An inclined support 19 extends rearwardly from the beam 9 and is suitably braced as shown at 20, said brace extending backward to the jack post 11. Another in- .clined support 21 extends rearwardly from the beam 5 and connected thereto is a brace 22 which is secured to the jack post 15 and extends across the support 21, there being a lever '23 pivotally connected to the lower end of said brace 22. J ournaled within this lever and within the upper end of the support 19 are the trunnions 24 of a drum 25 and secured tothis drum is a sand reel 26. An operating lever 27 is mounted at a suitable point upon the platform 8 and is connected to the upper end of the lever 23 by means of a rod 26 so that when the lever 27 is swung in one direction the drum 25 is shifted so as to swing the sand reel forward or backward.

Mounted on the beams 9 and 10 and above the sill 3 is a samson post 29 having inclined braces 30 and 31 secured thereto and to the beams 9 and 10 there being a rod 32 upon the upper face of the brace 31 which is bolted or otherwise secured to one of the beams 9 and 10 and to the upper portion of the samson post. Side plates 33 are fastened to the upper portion of the samson post and support a saddle 34 which is secured to the central portion of a walking beam 35. A stirrup 36 is arranged upon one end of the walking beam and is connected to a rod 37 which is provided adjacent its lower end with a slot 38 through which the wrist pin 18 extends. A post 39 is mounted upon the frame A close to the samson post and is connected thereto by means of braces 40 and rods 41. A band wheel 42 is secured upon the shaft 16 and disposed at one side thereof and rotatable therewith is a double tug pulley 43. The band wheel is adapted to receive power from a belt 44 or in any other suitable manner. A brake band 45 partly surrounds the sand reel and is secured at its ends tothe jack posts 11 and 15 by means of rods 46. By shifting the sand reel in one direction by means of the levers 23 and 27 it will be forced against the brake band 45 and held against rotation and by shifting it a short distance in the opposite direction it will be brought into contact with the band wheel d2 and be rotated thereby. Side braces l7 and 48 are disposed at one side of the samson post and are secured to the base frame A and these braces are similar to the braces 30 and 31 and a brace rod e9 similar to the rod 32 is disposed along the upper face of the brace as and fastened to the base frame A and the samson post. By means of the two sets of braces which have been described the samson post is held rigidly in an upright position and will resist all ordinary strains to which it will be subjected.

Arranged upon one end of the base frame A and preferably directly above the sill l is the derrick 50 upon the upper portion of which is journaled a crown pulley 52.

A lrum 6.9 is journaled between the lower portions of the uprights 5 0 and carries a bull Wheel and a tug pulley 71 adapted to receive power from the pulley 43 through a belt or cable 72. The tool carrying cable 73 of the machine extends over the crown pulley 52 and is adapted to be wound on the drum.

The actuation of the sand reel will of course be fully understood from the fore going description as will also that of the walking beam which is to be used for actuating the drill. The principal importance in the present case is attached to the construction of the apparatus whereby the same can be readily assembled at the point of use. It will be noticed that all of the parts are secured together by bolts and that the number of parts is reduced to the minimum. In order that tubing, drills, etc. may be conveniently brought on to the platform 8 a track 74 extends up to the platform from a point removed any desired distance from the machine and this track carries a truck 75 on which tubing may be conveyed into the apparatus. For instance if a ve-ry'long and heavy stem 76 is to be raised the rear or lower end is placed on the truck while the upper or front end is attached to the rope 73 and by pulling on this rope the front end of the stem will be raised and the truck will ride inward on the track carrying the lower or rear end of the stem. There is nothing to prevent this gradual upward swinging of the stem as would be the case if a fourcornered derrick were used. Should a portion of the well casing extend above the sur face of the ground or should other obstructions be located about the well opening the apparatus can be readily moved away from the well by disconnecting the sills 7 and 9 whereupon the machine can be moved sidewise. In order that the apparatus may be strengthened directly under the samson post 29 truss rods 3 are extended under the sill 3 and are secured to the ends of the beams E) and 10, as shown in Fig. 1. Trusses 35 are also used upon the walking beam as shown in said figure. This post 13$) is in- I clined as indicated and constitutes a stop to prevent beam 35 from moving downward against the derrick and damaging the machine or injuring the operator should the pitman 37 give way or should the outer end of the beam become loose from any other cause.
